I received a question about the medium Sudoku: should it be worthmore points than the current 2 ?

What do people think?

In terms of time taken versus points earned, it's definitely way out of line with most (if not all) other puzzles. So an increase in points awarded (maybe to 5 or thereabouts) would not be inappropriate, in my opinion.

Like Paul said, timewise it would be fair to give 4-5 points for the medium sudoku and about 2 for the easy one.It might go against the 'philosophy' of the site though, it being a calcudoku site. I leave that up to you though. Personally, it wouldn't bother me.
